TRANSOM-LIFTER.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed May 3, 1907. Serial No. 371,600.

T all whom it "may concern:

Be it hiown that I, CLYDE C. HALL, a citizen of the United States,residing at Bellaire, in the county of Belmont and State of Ohio, haveinvented new and useful Improvements in T ransom-Lifters, of which thefollowing is a specification.

This invention relates todevices for lifting or operating transoms, andit has for its object to provide a device of simple and inexpensiveconstruction which may be readily applied in position for operation, andby means of which a transom may be lifted to a horizontal position andsupported in such position.

Further objects of the invention are to simplify and improve theconstruction and operation of this class of devices.

\Vith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fullydescribed and particularly pointed out inthe claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention; it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawings, Figure 1 is a perspective view showing the improvedtransom lifter applied in position for operation to the transom over adoor, the housing or casing being removed. Fig. 2 is a side elevationshowing the device with the housing in position. Fig. 3 is a front viewshowing the device with the housing in position. Fig. 4 is a front viewshowing the device on an enlarged scale, the housing having beenremoved. Fig. 5 is a side view showing the device with the hous.

ing removed.

Corresponding parts in the several figures are denoted by likecharacters of reference.

1 designates a suitably bifurcated brac 'et or hanger having a screwthreaded shank 2 whereby it may be conveniently mounted in. position foroperation upon a door jamb 3 or in some other suitable position. Thehanger or bracket 1 constitutes a bearing for a shaft 4 carryin asprocket pulley 5 and having a crank arm 6 which latter may be of anysuitable length and is provided with a wrist pin 7 that is connected bymeans of a link 8 with a bearing 9 upon the transom that is to beoperated and which is shown at 10. Another sprocket pulley 11 issupported for rotation upon a suitable supporting member such as a screw12 which may be driven in the door jamb 3 in a position where it may beconveniently reached by the operator.

he sprocket pulley 11 has a crank arm 13 whereby it may be convenientlymanipulated, and said pulley is connected with the sprocket pulley 5 bymeans of a flexible member A preferably comprising short chain sections14 which are connected with each other by cords or wires 15; thisconstruction being resorted to not only on account of inexpensivenessbut also in order to permit the flexibl'e member A to be partly twisted,as is necessary for the reason that the sprocket pulleys 5 and 11 aredisposed in place at right angles to each other.

A casing or housing is provided, said housing being preferably composedof two parts or sections 16 and 17 containing respectively the pulleys 5and 11, andv the casing member 17 being provided with a slot 18 throughwhich the handle 13 projects.

For the purpose of retaining the parts in any of the various positionsto which they may be adjusted, there is provided a friction brake Bcomprising a spring coil 19 engaging the screw or supporting member 12of the sprocket pulley 11 and having arms 20 and 21, the former of whichis secured upon the 1 door jamb 3 by means of a staple 22 while the arm21 is formed with a bent portion constituting a shoe 23 and with aterminal prong 24 which projects through an aperture 25 in the casing orhousing. bent portion or shoe 23 of the brake member presses a portionof the flexible connecting member A into engagement with the adj acentwall of the housing, holding the same with sufficient force to maintainthe parts in N adjusted position. By pressure against the projectingprong 24 the pressure of the shoe 23 against the flexible member will bere vlaXed, and the parts may be freely adjusted.

The parts or sections 16 and 17 of the housing or casing are designed tooverlap, and one of said sections may be provided with slots 26 for thepassage of connecting screws 27.

Normally the c From the foregoing description taken in connection withthe drawings hereto annexed, the operation and advantages of thisinvention will be readily understood. By

turning the sprocket pulley 11 by means of the crank handle 13, motionwill be transmitted to the pulley 5 having the crank arm 6 which isconnected with the transom, thus efl'ecting adjustment of the latter.The parts may be retained in the position to which they are adjusted bythe friction shoe 23 engaging the flexible connecting member A andholding it in engagement with the wall of the housingor casing; bypressure upon the prong or finger piece 24:, the friction member may bedisengaged from the flexible connecting member, and the parts may bereadjusted as may be desired.

Having thus fully described the invention, What I claim as new is In adevice of the class described, a pair of sprocket pulleys, a transom,means for connecting the latter with one of the pulleys,

two pulleys, a casing or housing for the,

pulleys and the flexible element, a spring member coiled and supportedadjacent to the rear side of one of the pulleys and having armsextending therefrom, means for securmg one of said arms in a fixedposition, a shoe formed u on the other arm, said shoe engaging theexible element and forcing it into engagement with the wall of thehousing, and a terminal finger upon the shoe carrying arm extendingthrough an aperture in the housing.

In testimony whereof, I aflix my signature in presence of tWo Witnesses.
